When Dark Energy Turns On: Constraints on a Critical Emergence Model
Mahdi Najafi, Mahdi Habibollahi, Masoume Reyhani +4
We investigate a specific emergent dark energy scenario, known as critically emergent dark energy (CEDE), in which dark energy is effectively absent in the early Universe and becom…
A Multi-Probe ISW Study of Dark Energy Models with Negative Energy Density: Galaxy Correlations, Lensing Bispectrum, and Planck ISW-Lensing Likelihood
Payam Ghafari, Mahdi Najafi, Mina Ghodsi Yengejeh +3
We investigate the late-time imprints of three dark energy (DE) models, namely, the Chevallier-Polarski-Linder (CPL) parametrization, CDM, and an Omnipotent DE model, on…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
Dynamical dark energy confronted with multiple CMB missions
Mahdi Najafi, Supriya Pan, Eleonora Di Valentino +1
The measurements of the cosmic microwave background (CMB) have played a significant role in understanding the nature of dark energy. In this article, we investigate the dynamics of…
Robust Preference for Dynamical Dark Energy in DESI BAO and SN Measurements
William Giarè, Mahdi Najafi, Supriya Pan +2
Recent Baryon Acoustic Oscillation (BAO) measurements released by DESI, when combined with Cosmic Microwave Background (CMB) data from Planck and two different samples of Type Ia s…
Structure Formation in Various Dynamical Dark Energy Scenarios
Masoume Reyhani, Mahdi Najafi, Javad T. Firouzjaee +1
This research investigates the impact of the nature of Dark Energy (DE) on structure formation, focusing on the matter power spectrum and the Integrated Sachs-Wolfe effect (ISW). B…
